[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 13As shown, this embodiment proposes a wind and snow resistant cross-linked polyethylene insulated overhead cable, including a conductor 1, a shielding layer 2, an armor layer 3, and an outer sheath 4. The shielding layer 2 is made of polyethylene and is wrapped around the outside of the conductor 1. The armor layer 3 is wrapped around the outside of the shielding layer 2, and the outer sheath 4 is wrapped around the outside of the armor layer 3. It also includes a heating ring, a rotating tube 5, a scraping tube 6, a drive assembly, and a heating assembly.

[0021] like Figures 1 to 5 As shown, multiple heating rings are provided, and the heating rings are detachably mounted on the outside of the outer sheath 4. To achieve the detachable mounting of the heating rings, each heating ring includes two heating half-rings 101. Each heating half-ring 101 has a heating cavity inside. One end of each heating half-ring 101 is fixedly connected to a limiting tube 102, and the other end of each heating half-ring 101 has a limiting groove that matches the limiting tube 102. The limiting groove is connected to the heating cavity. The limiting tube 102 is detachably connected to the inside of the limiting groove by bolts. The two heating half-rings 101 can be connected by bolts, and the two heating half-rings 101 are spliced ​​together to form a complete unit. The ring is fitted outside the outer sheath 4. Multiple rollers 103 are rotatably arranged on the inner side of the heating half-ring 101. The rollers 103 are in contact with the outer wall of the outer sheath 4. The rollers 103 are parallel to the direction of the cable. The rotation of the rollers 103 can reduce the resistance of the heating ring rotation. At the same time, the rollers 103 provide resistance for the heating ring to move along the direction of the cable, ensuring the stability of the heating ring. The limiting tube 102 can improve the stability of the connection between the two heating half-rings 101. At the same time, the limiting tube 102 can connect the two heating half-rings 101, allowing hot air to flow inside the two heating half-rings 101.

[0022] like Figures 1 to 12 As shown, the rotating tube 5 is rotatably connected between two adjacent heating rings. The scraping tube 6 is connected to the rotating tube 5 and contacts the outer wall of the outer sheath 4. The scraping tube 6 is connected to the rotating tube 5 through the telescopic tube 7. The telescopic tube 7 is equipped with a compression spring 8 inside. The telescopic tube 7 includes two sleeves that are mutually sealed and slidingly fitted. A fixed plate is fixedly connected inside the sleeve. The compression spring 8 is connected between the two fixed plates. Under the action of the compression spring 8, the scraping tube 6 is pressed against the surface of the outer sheath 4, which can improve the heating and scraping effect of the outer sheath 4. Both sides of the heating half-ring 101 are connected to the connecting tube 9. The connecting tube 9 and the rotating tube 5 are connected through a quick connector. The rotating tube 5 connects multiple heating rings. The heating rings and the rotating tube 5 provide a certain degree of protection to the outside of the outer sheath 4, improve the strength of the cable, reduce the breakage of the cable in strong winds, and at the same time allow hot air to flow between multiple heating rings to heat and insulate the cable.

[0023] like Figures 1 to 13As shown, the drive assembly is used to drive the heating ring to rotate. The rotating tube 5 can rotate on its own axis while revolving with the heating ring. The drive assembly includes a mounting ring, a drive roller 201, a fixed internal gear ring, and a driven gear 202. The mounting ring is detachably mounted on the outside of the outer sheath 4. The mounting ring includes two mounting half-rings 203. One end of the mounting half-ring 203 is fixedly connected to a connecting plate 204. The other end of the mounting half-ring 203 has a connecting groove that matches the connecting plate 204. The connecting plate 204 is detachably mounted inside the connecting groove by bolts. The two mounting half-rings 203 can be connected by bolts. The two mounting half-rings 203 are spliced ​​into a whole ring that wraps around the outside of the outer sheath 4. The mutual limiting between the 04 and the mounting half-ring 203 can improve the connection stability between the two mounting half-rings 203. The drive roller 201 is rotatably mounted on the mounting ring, and a motor 205 is mounted on the mounting ring. The drive roller 201 is fixedly connected to the output end of the motor 205. An anti-slip pad 206 is fixedly fitted on the outside of the drive roller 201. The anti-slip pad 206 contacts the outer surface of the heating ring. The outside of the heating ring is provided with anti-slip texture. The fixed internal gear ring is fixedly connected to the mounting ring. The fixed internal gear ring is a spliced ​​structure and includes two half-gear rings 207. One end of the half-gear ring 207 is fixedly connected to an insert plate 208, and the other end of the half-gear ring 207 has an insertion part that matches the insert plate 208. The groove, with the connection between the two mounting half-rings 203, the two half-tooth rings 207 are spliced ​​together. The insertion plate 208 inserted into the slot can improve the stability between the two half-tooth rings 207. The driven gear 202 is fixedly mounted on the rotating tube 5. The driven gear 202 meshes with the fixed internal gear ring. To ensure the meshing stability of the fixed internal gear ring and the driven gear 202, the fixed internal gear ring is fixedly connected to the mounting ring through the fixing rod 209. Two limiting plates 210 are fixedly connected to the fixing rod 209. One of the multiple heating rings is located between the two limiting plates 210. Multiple balls 211 are rotatably connected to the limiting plates 210. The balls 211 contact the side wall of the heating ring. The mounting ring is installed at the end of the heating ring, positioning the heating ring between the two limiting plates 210. The motor 205 drives the drive roller 201 to rotate, thereby pushing the heating ring to rotate. The rotating tube 5 and the driven gear 202 revolve with the heating ring. During the revolution of the driven gear 202, under the action of the fixed internal gear ring, the driven gear 202 drives the rotating tube 5 to rotate. The rotating tube 5 drives the scraping tube 6 to rotate. As the scraping tube 6 rotates, it scrapes off the ice and snow on the surface of the outer sheath 4, reducing the amount of ice and snow remaining on the surface of the outer sheath 4. Under the action of the compression spring 8, the scraping tube 6 and the outer sheath 4 come into contact, and hot air enters the interior of the scraping tube 6, thereby transferring heat to the outer sheath 4 and reducing its freezing damage.

[0024] like Figures 1 to 11As shown, the heating assembly is used to supply hot air into the heating ring. The hot air circulates within the heating ring, rotating pipe 5, and scraping pipe 6 to heat the outer sheath 4. The heating assembly includes a heating chamber 301, a fan 302, and a transfer chamber 303. A heater 304 is installed inside the heating chamber 301. A temperature sensor 305 is installed on the heating chamber 301. The heating chamber 301 is connected to multiple air outlet pipes 306. The air outlet pipes 306 are connected to the heating ring on the side away from the drive assembly. Valves are installed on the air outlet pipes 306. The air inlet of the fan 302 is connected to the heating chamber 301. The transfer chamber 303 is fixedly connected to the mounting ring. Multiple air inlet pipes 307 are connected to the air outlet of the fan 302. The air inlet pipes 307 are connected to the transfer chamber 303, and valves are installed on the air inlet pipes 307. The transfer chamber 303 is rotatably connected to an air supply pipe 308. The end of the transfer chamber 303 near the heating ring is open. The open end of the transfer chamber 303 is sealed and rotatably connected to a rotating plate 309. The air supply pipe 308 passes through the rotating plate 309 and connects to the transfer chamber 303. The air supply pipe 308 is connected to the heating ring near the drive assembly. The air outlet of the fan 302 and the heating chamber 303 are connected to the heating ring 302. 1. Both are connected to a reinforcing pipe 310. The air inlet pipe 307 and the air outlet pipe 306 are connected to the corresponding reinforcing pipe 310 via flexible hoses and quick connectors. The reinforcing pipe 310 spans the two supporting structures of the overhead cable, further strengthening the overhead cable and providing support to reduce cable sagging caused by the weight of the heating ring and drive components. It also reduces cable bending or even breakage caused by wind and snow. The ambient temperature is monitored by a temperature sensor 305. The temperature sensor 305, heater 304, and motor 20 are all connected to the overhead cable. 5. Electrical connection: When the temperature is too low, the temperature sensor 305 transmits an electrical signal to the heater 304 and the motor 205. The heater 304 heats the air in the heating chamber 301. Under the action of the fan 302, the hot air in the heating chamber 301 enters the interior of the transfer chamber 303 and then enters the heating ring, rotating pipe 5 and scraping pipe 6 and flows back to the interior of the heating chamber 301 to realize the circulation of hot air. The heating ring, rotating pipe 5 and scraping pipe 6 heat the outer sheath 4, so that the overhead cable is in a higher temperature environment and avoids damage to the cable at low temperature.

[0025] It should be noted that the heating chamber 301 and the fan 302 are both installed on the building on which the overhead cable is erected, and are not installed on the cable itself. The fan 302, heater 304, motor 205 and temperature sensor 305 are all equipped with power supply equipment. The power supply equipment and the overhead cable itself exist independently and will not interfere with each other.

[0026] The working principle or usage process of this wind and snow resistant cross-linked polyethylene insulated overhead cable is as follows: Select an appropriate number of heating rings and rotating pipes 5 according to the length of the overhead cable. Divide multiple heating rings into a group according to the span of the overhead cable. Each group of heating rings corresponds to a drive component. This reduces the work done by a single motor 205 and adapts to the natural sag curvature caused by the large span of the cable. Use rotating pipes 5 to connect the heating rings. Install the heating rings on the outside of the outer sheath 4 with bolts. Install the mounting ring on the heating ring located at the end with bolts. Place the heating ring between the two limiting plates 210. The anti-slip pad 206 contacts the heating ring. The driven gear 202 meshes with the fixed internal gear ring. Connect the transfer chamber 303 and the air inlet pipe 307. Connect one of the connecting pipes 9 on the heating ring furthest from the drive component in each group to the air outlet pipe 306. Use a plug to seal the remaining connecting pipes 9 on the heating ring. Temperature sensor 305 monitors the external temperature. When the temperature is too low, temperature sensor 305 transmits electrical signals to heater 304 and motor 205. Heater 304 heats the air inside heating chamber 301. Under the action of fan 302, the hot air in heating chamber 301 enters the interior of transfer chamber 303 and then enters the heating ring, rotating pipe 5, and scraping pipe 6, before flowing back into heating chamber 301 to achieve hot air circulation. The heating ring, rotating pipe 5, and scraping pipe 6 heat the outer sheath 4, keeping the overhead cable in a higher temperature environment and preventing damage at low temperatures. When the cable is damaged, the motor 205 drives the drive roller 201 to rotate, which in turn drives the heating ring to rotate. Multiple heating rings and rotating tubes 5 revolve under the drive of the drive roller 201. When the driven gear 202 and rotating tubes 5 revolve, the driven gear 202 drives the rotating tubes 5 to rotate on their own axis under the action of the fixed internal gear ring. This causes multiple scraping tubes 6 to rotate on their own axis while revolving. The scraping tubes 6 contact the outer sheath 4, heating the outer sheath 4 while scraping off impurities and snow from its surface, reducing the residue of snow and ice on the cable surface, and further strengthening the wind and snow resistance of the overhead cable.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
